Summary: NullPointerException in LoadMgr3

Initial Comment:
This appears to be the same problem as issue 877172 
but manifested by jasper JSP compiles. This is running 
JBoss 3.2.3 using the stock embedded Tomcat. It is 
running under WinXP on Sun Java 1.4.2

The application (an EAR containing a simple WAR file) 
runs properly when the app is deployed for the first time 
or when JBoss has been restarted. When it is 
redeployed, the NPE occurs when the JSP display is 
attempted. This is highly reproducible and consistent. 
Simply restarting JBoss at this point resolves the issue; 
however, this will be difficult to support in both a 
development and production environment.

I'd be happy to provide additional information to assist in 
resolving this issue.

Thanks,

-Mike

Sorry for the delay...wanted to make sure there weren't huge 
dependencies to make the debugging insane.

To reproduce the error:
1. start JBoss 3.2.3 (Tomcat HTTP connector enabled on port 
8080)
2. deploy the attached EAR file (HtmlUiWebTest.ear)
3. make the following request: 
http://localhost:8080/HtmlUiWebTest/Common/TestPage1.jsp 
(replace localhost with name/IP of JBoss server)
4. simple JSP displays
5. undeploy the EAR file
6. when undeployed, redeploy the same EAR file
7. make the same request from step 3
8. NPE occurs in LoadMgr3
9. restart JBoss
10. make the same request from step 3
11. simple JSP displays

Let me know if you need any other config info. It is a slightly 
modified default server configuration (examples and JMS 
removed).

I need a reproducible testcase.
